Function core::arch::x86::_mm_mask_dpbusds_epi32

pub unsafe fn _mm_mask_dpbusds_epi32(
    src: __m128i,
    k: __mmask8,
    a: __m128i,
    b: __m128i
) -> __m128i

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Available on x86 and target feature avx512vnni,avx512vl only.

Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding signed 8-bit integers in b, producing 4 intermediate signed 16-bit results. Sum these 4 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
